IRA lVI. RADABAUGII, OF SPOKANE, WASHINGTON', ASSIGNOR TO LEE STRAUSS, 0F SPOKANE, WASHINGTON.

Application led July 28, 1919. Serial No. 313,816.

To all whom t may concern:

Be it known that I, IRA M. RADABAUGH, a citizen of the -United States of America, residing at Spokane, in the county of Spokane and State of Washington, have invented new and useful Improvements in Key-Fasteners, of which the following is a specication. n

This invention pertains to key fasteners and has for its object to provide an improved means for fastening the key in a door-lock afterI the door has been locked so that the lock'can not be picked from the opposite side of the door. rIhe fastener may also be used to fasten the key topreu vent the same from jarring out of the lock when the door is open.

The invention consists of an improved device for engaging the key and being anchored in the key-hole of the-lock. A detail description of the device will be hereinafter given and illustrated in the accompanying drawings, in whichigure l, is a view of the device complete,

Fig. 2, is a broken-away rear view of a containing a key and the key fastener, showing the bolt thrown into a locking position and the position of the key and the key fastener in the lock, e

Fig. 3, is a broken-away sectional view taken on the line 3-3 of Fig. 2, showing also a broken-away sectional view of a door in which the lock is placed,

Fig. 4, is a view of the key fastener in locking engagement with a key in the relative positions they are in whilein a lock, and

Fig. 5, is a sectional view tener taken on the line 5-5 of Fig. 4.

In a detail description in which like numerals refer to like parts throughout the several views, the key fastener 10 comprises a U shaped portion 11, a portion 12 integral therewith bent to a position at right angles with the U shaped portion, an intermediate portion 13 wherein the twist is made to effect the relative difference in positions of the portions 11 and 12, an opening 14 through the lU shaped portion 11, a vertically arranged lug 15 integral with the U shaped portion 11 and formed by turning to a vertical position the portion cut out to form of the key fasthe opening 14 in the lower wall of the U Specification of Letters Patent.

shaped portion "11, a member 15 hinged, as at 16, toa pivot 17 supported by upwardly projecting portions 18, the pivot 17 and portions 18 being integral with the U shaped portion 11, a tongue 19 integral with and cut out from the member 15, curved portions 20 and a` straight portion 21 integral With and cut out from the member 15.

In the practical use of the device, a key 22 is inserted into a lock 23 and turned so as to throw the bolt`24 outwardly into locking engagement with a door frame leaving the portion 25 of the key 22 and the handle in a horizontal position and at right angles with the key-hole 26 of the look 23. The key fastener 10 is then opened to the position shown in Fig. 1, the portion 12 inserted into the key-hole 26 of the lock 23 in the position shown in Figs. 2 and 13 with the `U shaped portion 11 engaging' the handle 27 of the key 22. The member 15 is then manually pressed downwardly forcing the tongue 19 through the opening 14 in the U shaped portion 11 and through the opening 28 in the handle 27 of the key 22, lodging the tongue 19 against the lug 15. The curved portion 20 locks over the rounded end 11a of the U shaped portion 11 and the parts are held in rigid relation holding the key-portions 25 and 27 in a horizontal position.

It will be seen that it will be impossible to remove the key 22 from the side 29a of the door 29 by an instrument inserted into the key-hole opening 30. The portion 11 of the key fastener holds the key-portion 27 as against rotation, the key-hole 26 in the lock 23 holds the portion 12 of the key fastener as against turning and the tongue 19 holds the key fastener 10 upon the key 22 as shown. The lug 15 serves as a stop against any instrument being inserted through the key-hole openings 26 and 30 to elevate the tongue 19 for the purpose of releasing the key fastener 10 and the locking engagement of the curved portions 20 with the rounded end 11a of the U shaped portion 11 is effective as against any casual release of the member 15 from its contact position with the U shaped portion 11.

When it is desired to remove the key fastener 10 from the key 22 the member 15 is manually elevated to the position shown in Fig. 1 by an upward pressure upon the portion 21.

What is claimed is:

l. A key fastener comprising a U shaped portion having slots in both walls and adapted for engagement with the key portion outside of the look and a portionvintegral therewith extending forward horizontally from the end of the lower wing of said U shaped portion for engagement in the key-hole of the look, a member hinged to the end of the upper wing of said U shaped member and adapted to extend rearward therefrom, the same being provided with a downwardly extending tongue adapted for passing through the slots in the walls of said U shaped portion and through the opening in the handle of the key, and with means for firmly engaging the rounded end of the U shaped member and means for releasing its engagement therewith.

2. A key fastener comprising a `U shaped `portion having slots in both walls and adapted for engagement with the-key portion outside of the look and a portion inteopes of this patent may be obtained for gral therewith, extending forward horizontally from the end of the lower wing of said U shaped portion for engagement in the keyhole of the look, a guard extending downwardly from the lower wing of said U shaped portion adjacent the slot therethrough and between said slot and the forward extending portion, a member hinged to the end of the upper wing of said U shaped member and adapted to extend rear ward therefrom, the same being provided with a downwardly extending tongue adapted for passing through the slots in the wall -of said U shaped portion, and through the opening in the handle of the key, and for bearing against the guard `extending downwardly from the lower wing of said U shaped portion.

In testimony whereof I affix my signature in presence of two witnesses.

IRA M. RADABAUGH.
